Radiant Roof Barrier Icicles

Attics heat up when the sun s radiant energy heats the shingles and the heat is transferred to the interior attic space through the roofing materials via conduction.

Radiant roof barrier icicles.

The hot roof material then radiates its gained heat energy onto the cooler attic surfaces including the air ducts and the attic floor. A radiant barrier works best when it is perpendicular to the radiant energy striking it. To understand this better consider a room with one light source in the form of an unshaded light bulb hanging in the middle of the room. Radiant barrier is a highly reflective material typically made of aluminum which blocks the transfer of radiant heat by reflecting it away from its surface offering a permanent way to reduce your monthly utility costs.

Increasing summer energy consumption and cooling costs. Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits. R 10 insulated radiant pex panel model ampex2015f 14 98 14 98. A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic.

This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern. Heavy duty perforated radiant barrier model rb4812550 67 95 67 95. Radiant barriers are utilized to reduce summer heat gain in attics. The roof still is gaining and loosing heat.

Set your store to see local availability add to cart. April 19 2019 posted in. Radiant barrier foil insulation systems block radiant heat energy instead of absorbing it like fiberglass insulation. Your radiant barrier makes the roof deck sheathing invisible from the attic.

The temperature of the attic space increases and that heat is transferred to the building below.
